A type of air purifier called an ozonator/ionizer air purifier can be used to add extra oxygen to your body. It is a simple way to enhance your health. Most everyone can use more oxygen.
We highly recommend this as part of every development program. Most people tolerate a small amount of ozone very well. A few have lung irritation from it, but in almost all instances, they solve this by just turning the ozone level down on the machine.
